Applicaon
The energy-meters “with a blue back-lighted LCD screen for prefect reading” are used to measure single-phase like
residenal, ulity and Industrial application. The unit measures and displays various important electrical
parameters, and provide a communicaon port for remote reading and monitoring. Bi-directional energy
measurement makes the unit a good choice for solar PV energy metering.

Output
Pulse Output
The meter provides two pulse outputs. Both pulse outputs are passive type.
Pulse output 1 is congurable. The pulse output can be set to generate pulses to represent total / import/export
kWh or kVarh.
The pulse constant can be set to generate 1 pulse per: 0.001(default) /0.01/0.1/1kWh/kVarh.
Pulse width: 200/100/60ms
Pulse output 2 is non-congurable. It is xed up with total kwh. The constant is 1000imp/kWh.
RS485 output for Modbus RTU
The meter provides a RS485 port for remote communication. Modbus RTU is the protocol applied. For Modbus
RTU, the following RS485 communicaon parameters can be congured from the Set-up menu.
Baud rate: 1200, 2400, 4800, 9600
Parity: NONE/EVEN/ODD
Stop bits: 1 or 2
